+##  This snippet preserves files during re-build.
+##  It supersedes other similar snippets - keep_*_keys.
+##  Put it in %pre section of the kickstart template file
+##  It uses preserve_files field which should contain a list of items to preserve
+##  This field for now could contain any of the following:
+##  'ssh', 'cfengine', 'rhn' in any order
+##  'rhn' part of this snippet should NOT be used with systems subscribed
+##  to Red Hat Satellite Server or Spacewalk as these
+##  have a concept of "reactivation keys" to keep the systems
+##  appearing to be the same.  Also do not use if changing
+##  base channels, i.e. RHEL4 -> RHEL5 upgrades.
